I'm running this compiler which is rather heap intensive and it crashed with a SigFault in calloc/malloc (I've tied both, but as expected calloc calls malloc) What suggestions are there further to track this down to the real problem. Giving that calloc/malloc should at least print something if it understands the error I expect heap corruption. No flags set in /etc/malloc.conf --WjW Program terminated with signal 11, Segmentation fault. Reading symbols from /lib/libc.so.5...done.
